TL;DR: This study reassess species relationships based on improved species sampling for Psilanthus, including P. melanocarpus, which increases the number of species in Coffea from 104 to 124, extends the distribution to tropical Asia and Australasia and broadens the morphological characterization of the genus.

TL;DR: This paper compiles, for the first time, the epithets associated with all taxa of cultivated potato, places them in synonymy and provides lectotype designations for all names validly published where possible.

TL;DR: A strategic and forward vision for conservation of plant diversity and sustainable use of plant resources in the 21st century is of far-reaching significance for sustainable development of Chinese economy and society.

TL;DR: A high level of endemic flowering plant species is highlighted for the first time for the southern Brazilian flora and their distribution in different biomes is analyzed, focusing on the Subtropical Highland Grasslands.

TL;DR: Maximum likelihood and Bayesian analyses of nrDNA and plastid DNA sequence data are presented for ‘C3Cyperus’ (Cyperaceae) and this study establishes a phylogenetic framework for future studies.

TL;DR: Morphological and molecular phylogenetics indicate that Dendrocoryne, Rhizobium and some other sections are not monophyletic, with morphological analyses providing the greatest resolution into groups corresponding with biogeography.

TL;DR: Information is provided on how to find out more about the research and courses available at the Free University of Brussels/Universite Libre de Bruxelles and the Institute of Systematic Botany in Zurich.

TL;DR: To be successful, the scientific contribution of botanic gardens need to be strengthened, as does government policy and commitment, and the commitment of significant new resources is an essential prerequisite for success, but this needs to be well coordinated, inclusive of all stakeholders and carefully targeted.

TL;DR: This poster presents a probabilistic reconstruction of the response of the immune system to Representative Tournaisia maritima, a type of “spatially aggregating virus” found in honey bees.

TL;DR: If a Target is to mobilize and focus resources to achieve tangible conservation outcomes, active participation of actors who are closely aligned to the scope of the Target may be more important than whether the Target is actually achievable.

TL;DR: Differences in floral development characters suggest that Helleborus and Nigella may not be closely related and possibly support placement into separate tribes.

TL;DR: It is suggested that future studies of evolution of climatic niches could be considerably improved by employing approaches enabling reconstruction of continuous response to climatic gradients.

TL;DR: A taxonomic revision of Allium in Korea and north-eastern China is presented based on critical observations of wild populations and extensive herbarium material, resulting in the recognition of 24 species comprised of 26 taxa, among which, four species and two varieties are endemic to Korea, and one species is endemic to China.

TL;DR: A combination of field observations, univariate analyses of leaf, floral and seed characters and principal coordinate analyses of floral characters in the context of a molecular phylogenetic analysis was used to investigate the patterns of variation and delimit morphological species anew in the genus Carapa.

TL;DR: These families are comparatively studied for the first time in terms of their floral morphology, anatomy and histology and overall floral structure reflects the molecular results quite well and Rhizophoraceae and Erythroxylaceae are well supported as closely related.

TL;DR: This first record of a non-flying mammal pollination syndrome in Ericaceae raises interesting new questions about the origins of the rodent pollination system and the selective factors that lead to its evolution.

TL;DR: It is shown theoretically how polyploidy causes speciation via cryptic reproductive isolation and can also cause radiations via epigenetically induced heterochrony and plasticity.

TL;DR: Five major clades are identified, of which four have strong geographical correlations, whereas the fifth corresponds to Iris section Physocaulon, and several species are placed with species not previously considered to be related.

TL;DR: Diversity in leaf morphological traits was assessed in 38 Greek Fagus sylvatica populations, covering the distribution of the species in the country, and two simultaneous trends appeared to be responsible for the existing diversity pattern.

TL;DR: In accord with previous estimates of Linoideae phylogeny, Linum is shown to be nonmonophyletic, with several segregate genera nested within it, but the relationships of the south-east Asian genera, Anisadenia, Reinwardtia and Tirpitzia, remain uncertain.

TL;DR: Total morphological and molecular evidence supports congeneric status for Ammannia, Hionanthera and Nesaea under the earliest name, Ammannias, and phylogenetic relationships of the four genera are hypothesized based on datasets from nuclear rDNA internal transcribed spacer (ITS) and plastid rbcL–trnF regions.

TL;DR: This work used AFLPs with six primer combinations to investigate 216 individuals in 38 populations of 16 different species of Leontopodium to clarify species relationships within the genus and to reveal information about the biogeography of the genus.

TL;DR: The authors' results indicate that a broad concept of Dichromanthus corresponds to a strongly supported monophyletic group sharing several ecogeographical attributes and at least one putative floral synapomorphy (nectary formed by a narrow channel at the base of the labellum).

TL;DR: The seed morphology of all Iranian annual species was studied, including E. aulacosperma and E.rhabdothos perma, both new records for Iran, using stereomicroscopy and scanning electron microscopy.

TL;DR: The phylogenetic relationships among three previously revealed genome size groups and among species of the highly polyploid genus Curcuma were evaluated using AFLP and it was found that hexaploid species exhibited significantly higher genetic diversity than higher polyploids.
